The AH-64D Apache Longbow is the new version of the Apache and a candidate to fulfil the attack helicopter and reconnaissance requirements of numerous armed forces.

The CH-47 Chinook is a heavy-lift high-altitude helicopter that can be deployed on a multitude of missions including military, humanitarian, disaster relief, search and rescue and firefighting missions in all climates and conditions.

Boeing Integrated Defence Systems vice-president and India country head Vivek Lall said that Apache will be a capable and lethal defender of India's troops and assets, while the Chinook will answer many of the country's military and humanitarian needs.

If selected, Boeing will build the Apache helicopters at its rotorcraft facility in Arizona and the Chinook helicopters at its rotorcraft centre in Pennsylvania.
